thought I had blown my head gasket, heard a pop then all hell broke loose, sounded like my exhaust was coming straight off the block it was so loud, no blue smoke though. upon further inspection I found the spark plug loose in my #1 cyllinder, plug wire was bent and real messed up, need to get an extension so i can get the plug out to check the threads. Anyway thats where I'm at with it, I would appreciate any helpful advice. Going to have to "shade tree it" myself.
